TimeWeaver release 18.10

Trace conversion

• Support for the Infineon MTV TAB trace format.
• Interactive MCDS tracing via Infineon DAS on TriCore AURIX devices.
• Improved interrupt handling and trace coverage for PPC NEXUS traces.
• Task switches can now be detected by specifying the memory cell that contains the current active task ID. You can specify using the global attribute running_task:

  attribute "running_task": address(("osKernelVariables"."ossActiveTaskIndex"));

• Routines can now be excluded from the analysis using the annotation not analyzed. The analysis then only considers the trace time for these routines.
• Traps are now handled like external routines.
• Improved handling for the GHS code factor optimization.

TimeWeaver analysis

• Performance improvements for trace-based path analysis.
• Improved loop scaling conflict detection.
• Traced execution times spent inside routines declared as external (using not analyzed) are now accounted for the annotated routine instead of the calling routine.
• Implemented support for overriding traced execution times of not-analyzed routines via the takes annotation.
• The analysis results can now be used in ResultCombinator.

Extended statistics

TimeWeaver statistics now include a polar chart view for trace segment and duration of interrupts.
